1 Claim. (Cl. 120-36) This invention relates to pencil eraserattachments and more particularly to an attachment for a pencil eraserthat is to be utilized with a typwriter in which the attachment isslidable on the pencil and is provided with a cup formation below theeraser to catch the particles erased from the surface of the paper whilein the typewriter.

It is an object of this invention to provide an attachment for a pencileraser which is utilized to catch the particles erased from a paperwhile mounted in a typewriter.

A further object of this invention is to provide a slidable attachmentfor a pencil eraser that may be utilized to catch particles that areerased from a paper while mounted on the roll in a typewriter.

A still further object of this invention is to provide a flexibletubular body in which an eraser is mounted in one end thereof and a cupis mounted in the opposite end thereof so that the tubular body may bebent to provide an eraser holder for a typewriter wherein the erasedparticles from the paper will be caught in the cup formation during theerasing operation.

A still further object of this invention is to provide an attachment forthe common disc erasers used in conjunction with a typewriter in whichthe attachment is a pivotally mounted catch all tray which will remainsuspended from the disc eraser to catch the particles erased from thepaper while the paper is mounted in a typewriter.

Further objects of this invention may be apparent by reference to theaccompanying detailed description and the drawings in which Fig. 1illustrates a side elevational view of the pencil eraser and cupattachment schematically illustrated with a typewriter roll and paper.

Fig. 2 is plan view taken on line 2-2 of Fig. 1,

Fig. 3 is a side elevational view of a further embodiment of thisinvention,

Fig. 4 is a side elevational view of a still further embodiment of thisinvention, and

Fig. 5 is a front elevational view taken on line 5-5 of Fig. 4.

Referring to Figs. 1 and 2 there is illustrated a pencil eraser providedwith an erasing material 11 and slidably mounted thereon is anattachment 12. The attachment 12 is shown as formed of a rigid materialsuch as sheet metal which may be readily formed with overlappingelements 14 and 15 which form the embracing portion of the clip, thatis, to embrace the barrel of the pencil 10. It is apparent that theelements 14 and 15 may be sprung outwardly to insert the barrel ofpencil 10 and likewise may be pressed inwardly to form a frictional gripwith the barrel of the pencil 10. The body portion 16 of clip 12 extendsbelow the pencil to form a cup shaped area 17. Likewise the cup shapedarea may be slightly wider than the clip formation formed by elements 14and 15. The cup formation should not be 2,933,066 Patented Apr. 19, 1960too wide as the attachment may remain on the pencil and be carried withthe pencil at all times. The cup formation 17 and particularly the edge18 should be formed smooth and round so that there is little or nopossibility of leaving a mark on the typewriter paper during an erasingoperation. Likewise the interior of cup 17 should be formed with a roughsurface so that the particles of erased material that fall therein willtend to remain within the cup and not be readily thrown from the cupduring an erasing operation. Of course it is apparent that after eacherasing operation that the cup 17 is to be cleaned. it is also apparentthat due to the small size of this attachment it lends itself to thesame erasing operation for each carbon copy and thus prevents the erasedparticles from falling between the papers and causing unsightly marks.

Referring to Fig. 3 there is illustrated a still further embodiment ofthis invention in which a flexible tubular body 20 is provided. The body20 may be approximately of the same size as a pencil or pen. Theflexible body 20 is provided with an eraser 21 mounted in one endthereof and is further provided with a cup shaped formation 22 mountedin the opposite end thereof. In use it is apparent that the flexiblebody 20 may be bent into the form illustrated in Fig. 3 and becomes aconvenient device for erasing especially with a typewriter when theparticles of paper are erased, the particles will drop into the cup 22.The cup 22 may be frictionally mounted within the tube 20 so thatregardless of' the position of erasing, the body 20 may be twisted orbent so that cup 22 will be below the eraser 21 and cup 22 may be turnedin body 20 so that its open end will always remain directly under theeraser 21.

Another form of this invention is illustrated in Figs. 4 and 5 in whichthe common disc eraser 30 is illustrated and attachment 31 is pivotallyafiixed to the disc 30 at its center 32 either with the metal barrelfound in the disc eraser or by using a separate pin 33 mounted throughthis barrel. The attachment 31 is generally triangular in sideelevation. Referring to Fig. 5 the attachment 31 is formed with an open.mouth area 34 which is the catch all. The mouth 34 is of coursesomewhat wider than the disc eraser 30 so that any twisting or turningof the eraser during an erasing operation will still drop the erasedmaterial into the mouth 34 of the attachment 31. The attachment 31 is soseated that the mouth 34 will always tend to press against the paper asit normally extends beyond the contact face of the disc 30 but since theatttachment 31 is pivotally attached, there is little or no pressure bythe front lip 36 of mouth 34. It is apparent in this embodiment that theeraser must be used in a vertical position although it may be twisted orturned slightly from the vertical in order that the catch all attachment31 may be effective in catching the erased material.

Various changes may be made to the embodiments disclosed hererin, thatis, the pencil eraser 10 may be entirely an eraser and not necessarily apencil and the attachment may still be utilized in the same fashion.Likewise, although the embodiment illustrated in Fig. 3 is suggested asa flexible tubular body, the complete structure may be similarlyconstructed of a flexible rubber as a single unitary structure withoutdeparting from the spirit of this invention. Although the catch alldevice illustrated in Figs. 4 and 5 is combined with a disc eraser, itmay be similarly formed wider to be attached to any flat type eraserwithout departing from the spirit of this invention and this inventionshall be limited only by the appended claim.

What is claimed is:
